Using technology as an aid to the geomorphologist part of Vignettes:Vignette Collection
Geomorphology requires characterization of the earth's surface at sufficient high resolution in 3 dimensions to explicitly represent landforms. Measuring change requires repeat survey, thus adding the 4th ...

Using geomorphology to determine tectonic slip at Wallace Creek part of Vignettes:Vignette Collection
The Carrizo Plain along the San Andreas fault in California is world-famous for its dramatic offset features. Sag ponds, linear ridges, beheaded channels and scarps define the landscape along the fault (Vedder and ...

Glacial Features of Franconia Notch, New Hampshire part of Vignettes:Vignette Collection
INTRODUCTION Franconia Notch, New Hampshire (Figure 1) is a classic northern Appalachian glaciated valley. It has geomorphic features from pre-glacial times, from the glaciation itself, from glacial meltwater, and ...

Karst Processes and Landforms on San Salvador Island, Bahamas part of Vignettes:Vignette Collection
INTRODUCTION San Salvador Island is located in the Central Bahamas, about 225 km ESE of Miami and is about 12 km north to south and about 5 km east to west (Figure 1). It is notable for being Columbus' first ...

Plateau Glaciers and their significance part of Vignettes:Vignette Collection
Plateaus exist in many mountainous parts of the world. Although not as spectacular as high, prominent peaks, they do often have (or have had in the past) glaciers associated with them. In this vignette I describe ...

Sinkhole hazard above salt, Dead Sea shore part of Vignettes:Vignette Collection
The hazard of sinkholes (collapse dolines) is commonly associated with karst (landscapes dominated by dissolution and subsurface drainage), where subsurface cavities undermine the overlying strata, causing ...

The Kern River, California: A Story of Uplift, Incision, and Flood Control part of Vignettes:Vignette Collection
Within Kern County, the present day Kern River is an example of two distinct river environments. In the Sierra Nevada, the Kern River is in a classic V-shaped canyon (Fig. 1) as it erodes towards base level. In ...

Uncovering Details of Glacial History by the Marks Left on the Land part of Vignettes:Vignette Collection
Glaciers can be thought of as large rivers of ice. One of the key elements that separates a glacier from an ice field is that a glacier more actively moves through the landscape, the mechanical properties of the ...

Rock Glaciers Move Mountains - Perhaps Right Under Your Skis part of Vignettes:Vignette Collection
What is a Rock Glacier?A rock glacier is an geomorphic feature that includes ice and talus. An "active" rock glacier meets two important criteria: 1) it contains ice currently and 2) it is moving and ...

Application of remote sensing in geomorphology part of Vignettes:Vignette Collection
Remote sensing is the observation of surfaces or objects while not being in direct contact with them. By this definition, cameras are remote sensors, observing the environment around us but not requiring us to ...
